A lack of goalscoring opportunities resulted in a goalless draw between the San Jose Earthquakes and the Colorado Rapids at the Buck Shaw Stadium.
The clearest of the chances in the first half fell to Colorado when Charles Eloundou struck a powerful effort straight at Jon Busch from a tight angle.
San Jose improved as the game progressed, and could have been ahead before the break when Shea Salinas was denied by Clinton Irwin after finding space inside the box.
The hosts should have broken the deadlock in the early stages of the second half, but Alan Gordon dragged a shot inches wide of the target following good work from Salinas on the wing.
Neither side seemed able to add a clinical finish to their promising play in the final third of the pitch, and despite a few late efforts from distance, the two teams were forced to settle for a draw.
